2 Samuel 17:2

And I will come upon him while he [is] weary With travelling, and with grief, and when endeavouring to get some rest by sleep, and so surprise him unawares, when not on his guard, and in no posture of defence:

and weak handed; while the number of men with him is small, and before the people from different parts can come to his assistance:

and will make him afraid; strike terror into him and his then, by surprising them suddenly in the night with such a number of men:

and all the people that [are] with him shall flee; one one way, and another another, for their own security, and leave David alone:

and I will smite the king only; dispatch him, and let the people flee without pursuing them.
